Fiberglass
Fiberglass ( American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non- conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surfboard
A surfboard is a narrow plank used in surfing. Surfboards are relatively light, but are strong enough to support an individual standing on them while riding an ocean wave. They were invented in ancient Hawaii, where they were known as ''papa he'e nalu'' in the Hawaiian language, and were usually made of wood from local trees, such as Acacia koa, koa. They were often over in length and extremely heavy. Major advances over the years include the addition of one or more fins (skegs) on the bottom rear of the board to improve directional stability, and numerous improvements in materials and shape. Modern surfboards are made of polyurethane or polystyrene foam covered with layers of fiberglass cloth, and polyester or epoxy resin. The result is a light and strong surfboard that is buoyant and maneuverable. Recent developments in surfboard technology have included the use of carbon fiber and kevlar composites, as well as experimentation in biodegradable and ecologically friendly resins ...

Glass Fiber
Glass fiber ( or glass fibre) is a material consisting of numerous extremely fine fibers of glass. Glassmakers throughout history have experimented with glass fibers, but mass manufacture of glass fiber was only made possible with the invention of finer machine tooling. In 1893, Edward Drummond Libbey exhibited a dress at the World's Columbian Exposition incorporating glass fibers with the diameter and texture of silk fibers. Glass fibers can also occur naturally, as Pele's hair. Glass wool, which is one product called "fiberglass" today, was invented some time between 1932 to 1933 by Games Slayter of Owens-Illinois, as a material to be used as thermal building insulation. It is marketed under the trade name Fiberglas, which has become a genericized trademark. Glass fiber when used as a thermal insulating material is specially manufactured with a bonding agent to trap many small air cells, resulting in the characteristically air-filled low-density "glass wool" family of produ ...

Owens Corning
Owens Corning is an American company that develops and produces insulation, roofing, and fiberglass composites and related materials and products. It is the world's largest manufacturer of fiberglass composites. It was formed in 1935 as a partnership between two major American glassworks, Corning Glass Works and Owens-Illinois. The company employs approximately 19,000 people around the world. Owens Corning has been a Fortune 500 company every year since the list was created in 1955. The Pink Panther acts as the company's mascot and appears in most of their advertisements. History 1935–1980 controversy Owens-Corning Fiberglass Company was formed in 1935 through the merger of Owens-Illinois and Corning Glass Works. It became a separate company in 1938 with its headquarters established in Toledo, Ohio. In 1938, the company sales reached $2.6 million. The company held its initial public offering on the New York Stock Exchange in 1952. In 1955, Owens-Corning purchased lan ...

Carbon-fiber-reinforced Polymers
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other ...

Glass Wool
Glass wool is an insulating material made from glass fiber arranged using a binder into a texture similar to wool. The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties. Glass wool is produced in rolls or in slabs, with different thermal and mechanical properties. It may also be produced as a material that can be sprayed or applied in place, on the surface to be insulated. The modern method for producing glass wool was invented by Games Slayter while he was working at the Owens-Illinois Glass Co. (Toledo, Ohio). He first applied for a patent for a new process to make glass wool in 1933. Principles of function Gases possess poor thermal conduction properties compared to liquids and solids and thus make good insulation material if they can be trapped in materials so that much of the heat that flows through the material is forced to flow through the gas. In order to further augment the effective ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Hammesfahr
Hermann Hammesfahr (February 20, 1845 – November 23, 1914) was a Prussian-American inventor who invented a type of fiberglass cloth in which glass was interwoven with silk. He was awarded the patent by the United States Patent Office in 1880. This was the earliest fiberglass of any kind that is known to have been patented. Family origins Hammesfahr was born in Evangelisch, Flachsberg, Wald Solingen, Rhineland, Prussia and died in Brooklyn, New York—the son of Carl Wilhelm Hammesfahr (1811–1878) and Caroline Wilhelmine Remschied (1806–1878). The Hammesfahr family is an old Solingen steel family tracing its roots back to the medieval armorer's guild. The "grandfather" of fiber optics This patent and a number of associated patents also provided the practical foundation for the development and production of fiber optics (Hammesfahr has been called “the grandfather of fiber optics”) and fiberglass. All were purchased by the Libbey Glass Company in Toledo, Ohio. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthopedic Cast
An orthopedic cast, or simply cast, is a shell, frequently made from plaster or fiberglass, that encases a limb (or, in some cases, large portions of the body) to stabilize and hold anatomical structures—most often a broken bone (or bones), in place until healing is confirmed. It is similar in function to a splint. Plaster bandages consist of a cotton bandage that has been combined with plaster of paris, which hardens after it has been made wet. Plaster of Paris is calcined gypsum (roasted gypsum), ground to a fine powder by milling. When water is added, the more soluble form of calcium sulfate returns to the relatively insoluble form, and heat is produced. :2 (CaSO4·½ H2O) + 3 H2O → 2 (CaSO4.2H2O) + Heat The setting of unmodified plaster starts about 10 minutes after mixing and is complete in about 45 minutes; however, the cast is not fully dry for 72 hours. Current bandages of synthetic materials are often used, often knitted fiberglass bandages impregnated with poly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swimming Pools
A swimming pool, swimming bath, wading pool, paddling pool, or simply pool, is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground (in-ground pools) or built above ground (as a freestanding construction or as part of a building or other larger structure), and may be found as a feature aboard ocean-liners and cruise ships. In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic, or fiberglass, and can be of a custom size and shape or built to a standardized size, the largest of which is the Olympic-size swimming pool. Many health clubs, fitness centers, and private clubs have pools used mostly for exercise or recreation. It is common for municipalities of every size to provide pools for public use. Many of these municipal pools are outdoor pools but indoor pools can also be found in buildings such as natatoriums and leisure centers. Hotels may have pools ...

Polyester Resin
Polyester resins are synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Maleic anhydride is a commonly used raw material with diacid functionality in unsaturated polyester resins. Unsaturated polyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers. Wall panels fabricated from polyester resins reinforced with fiberglassso-called fiberglass reinforced plastic (FRP)are typically used in restaurants, kitchens, restrooms and other areas that require washable low-maintenance walls. They are also used extensively in cured-in-place pipe applications. Departments of Transportation in the USA also specify them for use as overlays on roads and bridges. In this application they are known AS Polyester Concrete Overlays (PCO). These are usually based on isophthalic acid and cut with styrene at high levelsusually up to 50%. Polyesters are also used in anchor bolt adhesives though epoxy based mater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermosetting Polymer
In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening (" curing") a soft solid or viscous liquid prepolymer (resin). Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst. Heat is not necessarily applied externally, but is often generated by the reaction of the resin with a curing agent (''catalyst'', '' hardener''). Curing results in chemical reactions that create extensive cross-linking between polymer chains to produce an infusible and insoluble polymer network. The starting material for making thermosets is usually malleable or liquid prior to curing, and is often designed to be molded into the final shape. It may also be used as an adhesive. Once hardened, a thermoset cannot be melted for reshaping, in contrast to thermoplastic polymers which are commonly produced and distributed in the form of pellets, and shaped into the final product for ...

Glass Cloth
Glass cloth is a textile material woven from fiberglass yarn. Home and garden Glass cloth was originally developed to be used in greenhouse paneling, allowing sunlight's ultraviolet rays to be filtered out, while still allowing visible light through to plants. Glass cloth is also a term for a type of tea towel suited for polishing glass. The cloth is usually woven with the plain weave, and may be patterned in various ways, though checked cloths are the most common. The original cloth was made from linen, but a large quantity is made with cotton warp and tow weft, and in some cases they are composed entirely of cotton. Short fibres of the cheaper kind are easily detached from the cloth. In the Southern Plains during the Dust Bowl, states' health officials recommended attaching translucent glass cloth to the inside frames of windows to help in keeping the dust out of buildings, although people also used paperboard, canvas or blankets. Eyewitness accounts indicate they were not c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Games Slayter
Games Slayter (9 December 1896 – 15 October 1964) was a prolific U.S. engineer and inventor. He is best known for developing fiberglass, starting with a new method of producing glass wool in 1933. Biography Slayter was born in Argos, Indiana as Russell Games Slayter. He dropped ''Russell'' early in his life.
